There shouldn’t be a time limit to edit posts. Check to see that you have the latest version of your browser, and that you have deleted old cookies and disabled ad-blockers. Sometimes that helps to shake things loose a bit.
Hey @Robert Johnson , to answer your questions: 1. I can’t edit any of the three posts, including this current “Ask a Community” post. 2. No, I did not perform any change to my Miro profile or account since. I made a post last Friday, came back online on Monday(today), noticed I couldn’t edit anymore. 3. I also made another finding on this post, you can have a look at my previous comment.
